Title :
Flying q-bits and entangled photons for quantum cryptography

Abstract :
The excitonic ground state in a quantum dot shows a size- and shape-dependent two-fold splitting due to exchange interaction. By tuning the splitting q-bit emission from the exciton or entangled photon emission from the exciton/biexciton cascade are possible.
